CATEGORY 1: Newton’s Laws
This law states that an object in motion stays in motion unless acted upon by an outside force.
What is Newton’s First Law of Motion?
This force pulls objects toward the center of the Earth.
What is gravity?
This quantity measures how far an object moves in a certain amount of time.
What is speed?
When you slam on the brakes, your body moves forward because of this law.
What is Newton’s First Law (inertia)?
The product of an object’s mass and velocity is called this.
What is momentum?
This law can be summarized as F = ma
What is Newton’s Second Law of Motion?
This force opposes motion between two surfaces that are in contact.
What is friction?
The total distance traveled divided by total time gives this type of speed.
What is average speed?
Rockets launch into space by using this law.
What is Newton’s Third Law of Motion?
When no outside forces act, the total momentum of a system stays the same.
What is the Law of Conservation of Momentum?
According to this law, for every action there is an equal and opposite reaction.
What is Newton’s Third Law of Motion?
The force that acts on objects moving through air.
What is air resistance (or drag)?
When speed changes over time, we call this rate of change ___?
What is acceleration?
A skydiver reaches terminal velocity when this happens.
What is when air resistance equals the force of gravity?
Energy of motion is called this.
What is kinetic energy?
The tendency of an object to resist changes in motion is called this.
What is inertia?
The upward force exerted by a surface on an object resting on it.
What is the normal force?
If an object moves in a circle at constant speed, its velocity is changing because of this.
What is a change in direction?
Seatbelts are designed to protect you by counteracting this effect.
What is inertia (or momentum)?
Energy stored due to an object’s position or condition is called this.
What is potential energy?
A person pushes on a wall but it doesn’t move — this demonstrates which law?
What is Newton’s Third Law of Motion?
This type of force is exerted by a rope, string, or cable when it is pulled tight.
What is tension?
The slope of a distance-time graph represents this.
What is speed?
A ball thrown upward slows down because of this unbalanced force.
What is gravity?
When a roller coaster goes down a hill, this type of energy is transformed into another.
What is potential energy transforming into kinetic energy?
